SPECIFICATION forming part of Letters Patent No. 551,850,-dated December 24, 1895.

A lication filed March 28 1895. Serial No. 543;;47. on, modem Be it known that 1, ROBERT A. CHEsE BROUGH, oi the city and county of NcwYoi-k, in the State of New York, have invented a new and useful improvement in Apparatus for Urmnating (-arbage and other Refuse, of which the following is a specification.

This invention relates to apparatus for car rying out the process of crcmating garbage and other refuse which is the subject of my application .l'or Letters Patent No. 518,635), filed July 27, 150i, and which consists in passing the garbage or refuse continuously through a hollow shaft under the influence of gravity and subjecting it wdiile so passing to the action of a coking-iinne.

Theobject of my invention is, while pl) viding for a sutlicientlydre'c continuous descent of the garbage or refuse through the shaft, to retard its downward progress and re- ..tainit therein longenough to eti'cctits coking and to koep'it in such disintegrated condition as to prevent .ittromchoking theshat't and to permit the tree passage through it ol' the heat by which tlre coking is etl'm-ted.

in the accompanying drawings, Figure 1 represents a vertical section of an apparatus cont ructcd a cording to my invention. Fig. 2 represents ahorizontal section in the line 2 :2 of Fig. .I. Fig. 2) represents a vertical section at right angles to the section Fig. 'l of some of the details of the invention.

Similar letters of reference designate cor responding parts in all the figures.

A is an upright hollowshaft which may be from t'orty to sixty feet high, more or-less, and olf suitable horizontal dimensions, di vided by an uprightpartition (L which extends from the bottom nearly to the top thereof diilling llu: hollow shaft into a crcnialingchamber (1 and a fine D. The said shaft is represented as constructed of masonry lined t witlrtire-brick, and the said. partition is rcpresented as of tire-brick. "The said shaftis inelosed at the top by anarch directly under which on one side is a feeding-inlet o. fol'thc garbage or matter to be tfl'tllliltt l and on the og positcsi .le is an outlet- 1 above the part ition (7. tor the gaseous products ot comlnistion and cren'iation, the said outlet Z1 coinmnnicating with the upright line D. At or in war the bottom ot" this tlno l) is am ontlot d to the chamber E, in which is located a multitubular steam-generator F.

The crcmating-chamber has a hopper-like bottom c fitted with a sliding shutter f, which generally remains open for the discharge of the cremated matters into wz'igons G, which are run in and out to and from the lower part of the shaft under the said bottom, but which may be closed from time to time while one wagon is run out and another run in. Into the lower part of the cremating-chambcr there is represented as int roduced a burner g, which may be connected with any suitable means of supplying oil and steam for the purpose of producing the heat necessary to effect the coking or cremation.

Atthc end of the steam-gamma. or chamber E farthest from the ilue I) there is an outlet l: leading to a gas-scrubber I, which is interposed between the said. chamber if. and the smoke-stack or chimney J. The gas-s :rubber may be of any suitable kind. its purpose is to deprive the gaseous products ol' combust ion and cremation on their way toilie chimney 01' any ammonia they may contain, the said ammonia being collected. within the scrubber and the gaseous products thus doprivcd passing through the outlet 1' to the chimney.

Across the crcmating-chamber (7 there are arranged throughout the whole or the greater port ionof its height numerous bars K soseparated at. horizontal and vertical intervals that while the said bars suiiicicntly retard the downward progress of the garbage or material to be cremated and retain it. in the said chamber long enough to effect its coking or cremat ion, they permit a-sutliciently-frce continuous descent and. at the same time they cause the garbage in its descent to be kept so disintegrated that it will not choke the chamber and that the free upward passage through itot the heat by which its coking or cremation is cltcctcd will be permitted. 'ihcse bars may he arranget'l in any way at such various distanccs from the opposite walls of the chamber and at dill'crent heights that the bars at one level are opposite the intervals between the adjacent bars above and below them. They are represented as arranged in numerous horizontal ti rs on above anolherwith the bars of each iltl opposite the intervals.

' through. openings 1 Z in the side walls m of the 1 projects into the erenmting-chamber C an in.-

by any suitablemeens, by e'rota-ry shaft between those of the tiers innnediately above and below, so their while they suilieitmtly re- 1 tztrd the downward 11' gross of the material they will permit its sm'fieiently-i'ree descent. lhe rebirding-inns K may be of any suit-- able transverse section and of any suitable nntierisl and may be supported in any suit. able manner in the wells of the chamber, but I have represented. them (see Fig". 1) as of pol yg'onnl transverse section and as each composed of an external body of fire-elay and a tube or hol low core j of metal running lengthwise through said body, as shown in Fig. 3, for the purpose oi girin them the necessary strength. I have also represented (see Figs. 2 and 3) the said bars as being removable oremstingwlnnnber, the szu' d bars being somewhat longer than the illtOi'l'lill. width of the ehannben'ond entering and being supporied within the said openings. The said openings are represented (see Fig. as provided at the exterior of the walls 01. the chmnber with stops it n, by which to close them effectually when the apparatus is in operation, but are made removable for the purpose of removing and replacing; the bars.

Outside of the opening a of the cremati'ngchamber there is :1 eylinderL, which inclines downward toward and enters or is fitted to said opening and which has in its upper part an opening fitted with a hopper M, into which the garbage or matter to be cremated is fed in any suitable manner to keep up a supply to the cylinder. From the opening a there clined shelf or chute n, which forms at continuation of the bottom of the said cylinder. The snid'cylinder L is fitted with a piston p to which a reciprocating motion is imported q, furnished with it crank 'r and connected with said piston by rods 8 t and n. rodiusbar t. The said piston in its llpWitld reeiproent ing movement moves outward beyond the throat of the hopper and permits a portion. of the contents of the hopper to fa-l-i into the cylinder, and on its return movement it imshes the matter forward and into andv through the descends into the ereinnting-elnnnher. The forward or inward movement of the piston takes pleec only so for that a sul'fitnent portion of the material is retained in the opening 0. and on the chute It to-eonstitute a, seal. by which the said. opening is always left and kept closed against the escape of the gaseous products of combustion and cremation.

The steam-generator i is represented as fur nished with astemmdrum F, from which. in pipe 1 takes the steam where it is desired. to use it. The scrubber Iis represented. as fitted with a. pipe to with perforated branches to for the purpose of supplying iteiduleted water in showers for scrubbing the gas.

What I claim as my invention is- A refuse burner hevin g e substnntinliy vertical coking passage open throughout its length to permit the continuous downward movement of the material under the iniluintervals across the said coking passage for distributing the material and retarding. its continuous downward movement and intone for confining the coking flame and directing it upwardly throughout the downwardly moving materiel; substantially as set forth.
